Abstract: In this paper, a compact four asymmetric L-shaped slots loaded antenna has been designed for the wireless network & WiMAX applications. The antenna consists of four asymmetrical L-shaped slots with an area of 94 mm2 , 66 mm2 , 44 mm2 & 28 mm2 respectively & probe fed provides for the excitation to the antenna. The antenna can be operated between 2.6 GHz to 5.4 GHz frequency range. The proposed antenna resonant at three different frequencies as 2.95 GHz, 4.85 GHz & 5.23 GHz & the return loss are -16.5 dB, -13.6 dB & -14.6 dB respectively. It produces one linear polarization at 2.95 GHz frequency & two circular polarizations at frequencies 4.84 GHz & 5.21 GHz. The proposed antenna finds its application in WLAN (2.94-3.05) GHz, WiMAX (4.81-4.92) GHz & IEEE 802.11a (5.15-5.35) GHz. The proposed antenna simulation results show that good radiation pattern with multi frequency band in comparison of reported designs.
